CDFW is intending to execute a Lake and Streambed Alteration Agreement Pursuant to Section 1602 of the Fish and Game Code (# 1600-2016-0259-R5) to the project applicant, San Diego Association of Governments. Project activities include construction of an approx. 240-foot long bridge parallel to the existing Santa Fe Street bridge, construction of a bench along the eastern bank of Rose Creek created by a cut into the bank for the eastern side of the bikeway and a retaining wall for the western side, and construction of a structural slab over a lightweight cellular concrete abutting the existing bridge wall for both the I-5 freeway and Mission Bay Drive bridges. Construction may be phased. Grading may involve the net movement of approx. 8,976 cubic yards (cy), including 1,974 cy structural for bike path, 740 cy of wall installation, 1,866 cy of concrete/rock backfill, 376 cy of rock slope protection, and 4,020 cy of channel clearing. There is 954 cy of removal/reuse of existing rock slope protection (not included in the net movement total above), and unsuitable material will be exported. The project proposes to permanently impact 0.66 acre of streambed, including 0.40 acre southern riparian forest, 0.08 acre southern willow scrub, 0.04 acre freshwater marsh, 0.04 acre non-native riparian, 0.09 acre streambed, and 0.01 acre concrete-lined channel, and temporarily impact 1.149 acre of streambed, including 0.68 acre southern riparian forest, 0.19 acre southern willow scrub, 0.14 acre freshwater marsh, 0.18 acre non-native riparian. 0.03 acre tamarisk scrub, 0.14 acre streambed, and 0.13 acre concrete-lined channel. Project impacts will be mitigated through the creation, restoration, and/or enhancement of 1.64 acres riparian scrub/woodland/forest habitat.
